Example of your titles for the #ulog series:

Ulog 1: the title of the post

or

#ulog #1 ~ the title of the post

Basically you would number it each time. #ulog 2, #ulog 3 etc

Does that make sense?

The reason I think ulogs are great, is that for a ulog you don't have to make it a huge post, you can even just put one photo of the day and a little paragraph or two about your day, your experience, or whatever the photo is of. It encourages people to post every day, even if it's not a big elaborate post.
